Definitions
- the invention relates to a transmit / receive module of a active phased array radar comprising a Circuit arrangement for connecting a transmitting / receiving device to a transmitting / receiving path and a Transmit / receive path.
- Transmit / receive links are usually in the form of Wired or wireless connections or as a combined Wired and wireless connections realized. At the ends of the Transceiver are corresponding transceivers connected.
- transmission / reception systems of this type are designed so that the transceivers during the Transmission mode can not receive and vice versa during the receiving company can not send.
- transceiver systems are called Narrowband transceiver systems operated.
- Systems of this Type work only in one or more predetermined narrow Frequency bands, between those during operation is switched back and forth.
- the location of the frequency bands can be up to the microwave or millimeter wave range pass. Accordingly different are also the circuit-technical requirements and boundary conditions, those in the design of the send / receive channels such Narrowband transmitting / receiving systems are to be noted and the especially in systems operating in different frequency bands can be operated, a considerable circuit engineering Expense result.
- analog narrowband multichannel transmit / receive systems for the microwave range are different signal conditioning necessary to a message processing to carry out.
- Circuit configurations such as Frequency converters, modulators, Amplitude and phase adjuster, switches for the appropriate application are optimal.
- To adjustment the function requires converter circuits, e.g. generate an analog variable from a digital data word.
- EP 0 622 908 A2 describes a circuit arrangement for connecting a transmitting / receiving device to a transmitting / receiving path, which includes a reference oscillator which can be connected via a first switch either to a first mixer in the transmitting channel or to a second mixer in the receiving channel. Between the first mixer and the transceiver, a second switch is connected. The two switches are connected by a control that in the transmission case, the reference oscillator is connected to the first mixer and the transmission channel is turned on and the receiving channel is interrupted and that in the case of reception, the reference oscillator is connected to the second mixer and the receiving channel is turned on and the Transmission channel is interrupted.
- the object of the invention is a Transmit / Receive module of an active phased array radar to do that with as few as possible structural change and adaptation measures for different Operating frequency bands will be used can.
- the essential advantage of the invention is to be seen in that by the formation of the circuit arrangement according to the invention between transceiver on the one Page and send / receive path of the transmit / receive module on the other hand it is now possible to get one standardized transceiver type for a wide variety of Operating frequency bands from a particular Frequency range to use.
- Circuit arrangement initially in this frequency range for all operating frequency bands are equal, i. standardized is, both the transmitter / receiver type as well as the inventive circuit arrangement cost in produced in large quantities and easily in the individual (and usually still individually conceiving) transmission / reception routes are integrated.
- both the same circuit arrangement S is the transmit channel and E the receive channel denotes, with A the circuit arrangement side, at the the transceiver (not shown) is connected, and B, the circuit arrangement side at which the (also not shown) transmitting / receiving path connected is.
- a reference oscillator (“Local Oscillator (LO)" is over a first switch 2 with a first mixer 3 or connectable to a second mixer 4.
- the first mixer 3 is in the transmission channel S, the second mixer is in the receiving channel e arranged.
- Transceiver Between the first mixer 3 and the (not shown) Transceiver is a second switch 5 switched and between second mixer 4 and transceiver is a third switch 6 connected. Of the second and third switches 5, 6 are connected to each other. All three switches 2, 5 and 6 are from a common Control 7 controlled.
- the frequency of the side A of the transceiver in the transmission channel S fed transmission signal in the Operating frequency band of the transmitting / receiving path (page B) transform and vice versa the frequency of the transmission / reception path (Page B) fed into the receiving channel E.
- FIG. 3 The implementation of the invention in a monolithic integrated Circuit for a T / R module of a phased array radar is in FIG. 3 shown.
- On display is a silicon-based manufactured first semiconductor chip 11, on which a preferred embodiment of the invention Circuit arrangement (with the exception of a) of the reference oscillator (1 in FIG 1 and FIG 2) and b) as discrete Component formed control (7 in FIG. 1 and FIG. 2)) has been realized as a monolithic integrated circuit is.
- the chip 11 is arranged on a substrate 17, arranged on the circuit parts of the transmission / reception path are gallium arsenide-based monolithic integrated and connected to the circuit on the silicon chip 11 are.
- the circuit on the Si semiconductor chip 11 differs differ from the basic illustration in FIG. 1 or FIG. 2 only in that between the second and third switch 5 and 6 additionally a phase shift member 8 and a first amplifier 9 are connected, both of which Control 7 can be controlled.
- the (not shown here) Reference oscillator LO is via the first switch 2 either with the first mixer 3 in the transmission channel S or with the second mixer 4 in the receiving channel E connectable. Not that one shown) transceiver is connected on the side A.
- the first mixer (3) is on the output side over two second GaAs-based monolithically integrated amplifiers 12, 13 connected to the first port of a circulator 14.
- the second gate of the circulator 14 is also on one GaAs-based monolithic integrated limiter 15 and third Amplifier 16 connected to the second mixer 4.
- the third gate of the circulator 14 is connected to a connection point (S / E) for the transmit / receive antenna (not shown) (page B) connected.
- the two second amplifiers 12, 13 and the third amplifier 16 are also from the drive 7th driven.
- the switch position of the three switches 2, 5 and 6 corresponds the switch position according to FIG. 2 ("Reception case”). In the “transmission case” all three switches 2, 5 and 6 are synchronous switched to the other switch position, which is the Switch position according to FIG. 1 corresponds.
- the from the (not shown) antenna received signals via the circulator 14, the limiter 15 and the third amplifier 16 on the second mixer 4 given there with the over the first Switch 2 is also given to the second mixer 4 Output signal of the reference oscillator LO in the receiving frequency range of the transceiver (not shown) mixed, via the third switch 6 the phase shifter 8 (to adjust the phase of the mixed received signal) and the first amplifier 9 (for the purpose of adaptation the amplitude of the mixed received signal) and from there via the second switch 5 to the receiving channel of the (not shown) transmitting / receiving device forwarded. So while the receiving channel E switched through is, the transmission channel S is interrupted twice (by the two switches 5 and 6).
- the circuit arrangement according to FIG. 4 is different from the according to FIG. 3 only in that the transmission channel S and the receiving channel E transmitting / receiving side (page A) on the Si semiconductor chip to a common transmit / receive channel S / E are summarized by the connecting lines from the second and third switches 5 and 6 to the transceiver to a connection point 10 a common connection line has been summarized are.
